A novel solution to optimal power flow problems using composite differential evolution integrating effective constrained handling techniques.

Optimal power flow is a complex and highly non-linear problem in which steady-state parameters are needed to find a network's efficient and economical operation. In addition, the difficulty of the Optimal power flow problem becomes enlarged when new constraints are added, and it is also a challenging task for the power system operator to solve the constrained Optimal power flow problems efficiently. Therefore, this paper presents a constrained composite differential evolution optimization algorithm to search for the optimum solution to Optimal power flow problems.
